Q80
The variables whose coefficient vectors are unit vectors are called ____________.
A.
Unit Variables
B.
Basic Variables
AnswerC.
Non basic Variables
D.
None of the above
Answer: Option B
Solution
Answer: Option B
Solution:
The variables whose coefficient vectors are unit vectors are called basic variables. The basic variables can be defined as the m variables which can take any value other than zero. Moreover, if the variables satisfy the non-negativity condition of the LP model, the basic solution created by them is called the basic feasible solution. The remaining variables are known as the non-basic variables.
